<h2>Why is this an issue?</h2>
<p>The repetition of a prefix operator (<code>!</code>, or <code>~</code>) is usually a typo. The second operator invalidates the first one.</p>
<pre>
int v1 = 0;
bool v2 = false;

var v3 = !!v1; // Noncompliant: equivalent to "v1"
var v4 = ~~v2; // Noncompliant: equivalent to "v2"
</pre>
